1 Objects 'ofthepresent invention are t'opro vide outlet apparatus for ashbunkers such as are arranged under boilers and discharge into water sluices or other conveyors, which will entirely close the outlet and thus prevent air from entering the furnace by way of that outlet, which will feed ashes and clinker, and

which will crush clinkers of considerable size.

Other objects of the invention willappear from the following description but it may .be said that the invention, generally stated, comprises outlet apparatus forashbunkers including a frame and a plate horizontally reciprocatable in respect to the frame and adapted to operate as a gate and'a'feederIand a clinker crusher. I f s V The invention also comprises the improvements to be presently described and finally In the following description reference will be made to the accompanying drawings forming part hereof and in which Figure 1 is an elevational view partly in section and partly in elevation illustrating ash hoppers provided with outlet apparatus embodying features of the invention and showing also a part of an ash bunker.

Fig. 2 is a view in parta transverse section taken on the line 2-2 ofFig. 1.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2. p 7 V Fig. 4 is an end view partly in section similar to Fig. 2 and illustrating a modification, and

Fig. 5 is a detail sectional View illustrating a modification of the clinker crusher shown at the righthand lower portion of Fig. 2.

Referring more particularly to Figs. 1 to 3, 1 is a plate mounted for horizontal reciprocation. Referring'to Fig. 2 the lefthand portion of this plate 1 always underlies the discharge opening 2 at one side of the apex of the hopper 3 of the bunker 4. The righthancl portion of the plate 1 covers and uncovers the inlet opening 5 to a conveyor which happens to be shown in the form of a sluice 6, which, however, is merely typical. There is a frame 7 with which the end i 8, shown as beveled to an edge, of the plate 1 cooperates. 10 is an enclosure on both sides i vidediwith a pitman mechanism 15 is a means and at the top of the plate 1 aiid'atone it is in open communication with the outlet 2, and a t the other end itis upwardly in;

clined as at 11 and provided withan upwardly opening normally. closed door 12, hingedat13. V

The mode of operation may be described as fOllOWSt l V r j When the plate'l is in reciprocation it continually feeds ashes and clinker from the hopper to the inlet 5 of the conveyor. Y Ashes and small clinker drop through theopen} ing' 5. Larger clinkers are crushed between; the end 8 of the plate and the frame; 7 to pieces of suchsize that theyfall through the opening 5, and still larger clinkers, under the feeding action of the plate 1, are pushed up the'incline 11 .and opening the door 12 ill) give notice that theirremoval is required.

Obviously the rate of ash feed to the conveyor may be adjusted and thereafter kept constant by changing the speed of thefplate 1, by changing the throw of the plate .1. in respect to the frame 7 andby adjusting the position of the throat, plate 2 1, Or by a com-v ination of these. The adjustment ofthroat plate 24 maybe made by loosening the. un-

numbered bolts which hold the throat plate 24 to theincline 11 and moving'the bolts in slots (not shown in the drawings asthe scale is small) which may be'provided in the plate or infthe "incline or in both. Another method of adjustment is to remove the throat plate 24 and to substitute another of different size.

' When itis not desiredto remove ashes and Itis an advantage that the rate of feed to the conveyor may' be proportioned to its capacityand it is an advantage of the struc; ture that it takes up verylittlc head room,

andsince apparatus of thisitype islusuallyf located in basements and the like under; boilers, the matter of head room is important.

A car 14 arranged to travel on tracks aligned with a series of hoppers and pro;

for operating a series of the described plates 1. The rod 16 of the pitman mechanism is arranged as indicated at 17 for detachable connection with the plates 1, so that the car may travel along and be connected with the plates of the series so as to reciprocate them one at a time. When at rest the plates 1 are in position to close the outlets The pin and slot connection 18 are a means for varying the throw of the plates 1, and the motor on the car is a means for varying the speed of reciprocation of the plates 1.

The construction and mode of operation of the modification shown in Fig. 4- are as above described except that the car 19 carries the reciprocating plate 1, the frame 7, the housing 10, and the pitman mechanism 20. Each hopper 21 is provided with a gate 22 and the outlet to the conveyor is provided with a lid 23. \Vhen. the outlet apparatus is in position under a hopper 21, the lids 22 and 23 are open so that the hopper discharges into the enclosure 10 and onto the plate 1, but when the outlet apparatus is not under a hopper, its gates 22 and 23 are closed;

In order to permit the device to crush large lumps down to PIGClBtQlIDlDCd size use may be made of an inclined crushing throat 8 and 24 in association with the plate 1 however reciprocated horizontally. I

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.

I claim:

1. Outlet apparatus for ash bunkers comprising a hood open at one end for the reception of ashes and clinker and having at its other end an upwardly and outwardly inclined portion and an outwardly opening door, said hood having near the closed end a frame providing an outlet, and a plate reciprocatably mounted across said outlet at the lower portion of the hood and adapted to operate as a gate and a feeder and a clinker crusher.

2. In combination an ash bunker having an outlet, a conveyor having an inlet arranged to one side of the outlet, a horizontally reciprocating plate of which one edge portion underlies the opening in all positions of the plate and of which the other edge portion covers and uncovers the conveyor inlet, an air-tight enclosure enclosing the plate, said plate acting in cooperation with the enclosure as a gate and a feeder and in cooperation with the wallof the inlet which confronts its end as a clinker crusher.

3. Outletapparatus for ash bunkers including a hopper having an outlet adjacent its bottom, a frame of which a part underlies said outlet and of which the remainder extends laterally away and surrounds a conveyor opening spaced from beneath said opening in said hopper, a plate received in said frame and underlying said opening in said hopper and overlying said conveyor opening and horizontally reciprocatable in respect to the frame to provide a gate for material in said hopper by holding said material in the opening in said hopper and to feed material from said opening in said hopper to said conveyor opening and to cooperate with a portion of said frame to crush material therebetween, and an air-tight hood surrounding and enclosing the o ening in said hopper and said plate and said conveyor opening to prevent the escape of dust from the material thereon.

4. Outlet apparatus for ash bunkers including an air-tight hood adapted to receive ashes and to deliver the same and to revent the escape of dust from said ashes uring said reception and delivery, a plate reciprocatably mounted at the bottom of said hood and adapted to operate as a gate by holding ashes in a pile on entering said hood and to operate as a feeder by conveying the ashes through said hood and to operate as a clinker crusher by pressing at one end on clinkers, and a frame surrounding said plate and having an adjustable throat piece opposite the end of said plate to cooperate therewith to crush clinkers therebetween.
